Very good neutral-stable midrange disc. Tales of the Claymore being a flippy disc seem to be vastly exaggerated, though that might just be the result of the Frost Line plastic adding some extra stability to the disc. I would definitely recommend getting a max weight disc in Frost Line or Opto plastic if you plan to throw it off the tee. If you want a more understable mid that you can use to shape shots through the woods though, you might get a GL or Retro Claymore instead, since in my experience those plastics tend to be a little less stable. Pick whichever plastic you want for your intended use, but I've been using the Frost Line version, and that's the 5 star disc to me.
The Claymore has a surprisingly neutral-stable flight that lends itself best to straight shots and gentle gliding hyzers. You can force it over on an anny if you want to, but you won't turn it over by accident unless you throw it into a stiff headwind. Mostly it just seems to flip to flat and hold straight if you give it a hard throw with clean form, and that's really all I want out of a mid. I pair it with a more understable and a more overstable mid to fill out my bag, and the Claymore sits neatly in the middle. For me, this disc maxes out at about 280 feet, which is a pretty long distance for a mid considering that I might throw a distance driver out to about 350 on a good day. The Warship and the Gobi are still slightly longer than the Claymore, but the Claymore definitely comes close to the furthest flying midranges on the market.
Regarding the shape and hand feel of the Claymore, it seems to be designed like a driver with a slightly thinner rim. It has no bead, not even the sort of microbead that you find on a Fuse or a Truth. Despite having no bead, it still has the same depth on the inside of the rim as most beaded midranges, so you get the usual hand-filling midrange feel without the incongruity of that little bump under your finger. The straight up and down inside wall of the rim seems to be begging for you to power grip it rather than fan grip it, though you could probably do either depending on what you're more comfortable with. The design is very simple, but undeniably effective.
Overall, I would recommend this disc to beginners as well as other intermediate players like me. It might be a little flippy for the power throwers that want to be able to throw their mids 400 feet, but for the other 99% of the disc golfers in the world this will be a great disc because it offers an awesome combination of distance and control for both upshots and drives off the tee.
